I am the best in the world with the crime solving system

While speaking, he ran out with the hemp rope.

The hemp rope is as thick as a little finger.

There is also a faint medicinal scent.

Chen Chaoyan took it over, and during the inspection, the yamen servant claimed credit: "This hemp rope should be used by the Ma family to bind medicinal herbs. When I searched the yard in front, I saw several bundles of medicinal materials using such hemp rope. "

"Not bad." After Chen Chaoyan praised, he used the magnification function of the light screen to find a few residues of medicine and dander on the hemp rope. After confirming that it was the tool used to strangle Li Er, he did not relax his vigilance and used it again. The light screen compared the cable groove on Li Er's neck.After matching again, he asked, "Where did you find it?"

The yamen servant replied: "Under Li Er's bed."

Chen Chaoyan's gaze sank slightly, "Just under the bed?"

The yamen servant nodded, "It's under the bed, you can see it when you lower your head."

"Go ahead and continue the search." Chen Chaoyan ordered.

After the yamen servant left, she looked at the hemp rope, raised her eyebrows and said, "That's not right."

After finishing speaking, regardless of Xie Xuan beside him, he immediately went out and went around to the mud pit where Li Er's body was found.The Ma family was taken by Chonglou to the front yard where the guests were treated, and Li Er's body was also carried away by the yamen servants.After walking around the mud pit twice, Chen Chaoyan walked under the maple and poplar tree, and observed the traces on the wall along the base of the wall.The fence here is much higher than that of the Zhou family. After Chen Chaoyan inspected the wall and found nothing, she reluctantly asked Ruo Lanfei to climb up the tree. After inspecting the top and outside of the wall, she found nothing abnormal. Frowning his eyebrows, he returned to the courtyard where Ma Huai lived.

Xie Xuan has been standing in the yard waiting for her.Seeing her come back, he asked, "What's wrong?"

After thinking about it, Chen Chaoyan said: "There are Li Er's portraits on the streets and alleys of Luyang County. Not long ago, Mr. Feng also increased the reward to two rounds. With such a heavy reward, it is impossible for Li Er to hide around. .Then the biggest possibility is that after Li Er fled, he hid in Ma's house. What's more, he hid in Ma Huai's courtyard."

Xie Xuan nodded in agreement, "I have already asked Lingyou to go back and inform Mr. Feng that he will send someone to arrest everyone in the Ma family."

Chen Chaoyan ignored his answer, but continued to say: "According to the speed of our investigation, Ma Huai should have known about the Ma family's investigation today. And he will occasionally follow us to participate in the investigation. He should be well aware of the intensity. If so, why would he kill Li Er at this juncture?"

"You went back just now, just to find evidence that he is not the murderer?" Xie Xuan asked clearly.

"Not really." Chen Chaoyan looked at the hemp rope in his hand and said.She just felt something was wrong.

Xie Xuan also looked at the hemp rope in her hand, and said after deliberation: "Is it possible? Ma Huai knew that Li Er could not continue to hide with him because he understood the progress of our investigation, but there were his pictures everywhere outside. With so many rewards for the portrait, it is even more impossible to escape. So after weighing the pros and cons, kill him?"

"As for why such a conspicuous flaw was left, it is very likely that after he killed Li Er first, Mr. Feng ordered the judiciary and the sihu to conduct a self-examination and trapped him in the sheriff's mansion."

"No." Chen Chaoyan shook his head, "You forgot the case of Zhou Zhongcai and Shi Zhi."

"Why do we spend so much effort to investigate?"

"Because whether it is Zhou Zhongcai's case or Shi Zhi's case, they can be called the closest to 'perfect' cases. We have no other way but to investigate one by one in a stupid way."

"But when you look at the case of Li Er's murder, the body and the murder weapon are all too simple, as if someone put them here deliberately, waiting for us to find them."

"That's right," Yuejian interjected, "Why did Ma Huai do this? It was because he knew he couldn't escape, so he just broke the can and threw it?"

Chen Chaoyan looked at Xie Xuan and said nothing.

Xie Xuan took the hemp rope in her hand, smelled the faint scent of medicine on the hemp rope, and said, "If the murderer wasn't Ma Huai, who would it be?"

Yuejian looked at Chen Chaoyan.

Shishu, Wenmo and Ruolan also looked at Chen Chaoyan.

Chen Chaoyan looked at the hemp rope in his hand, and said as impartially as possible: "No matter who it is, Li Er's body was found at Ma's house, and it has nothing to do with them no matter what!"

Xie Xuan was about to say 'not bad' when the previous yamen servant ran out again.

This time, he held a sandalwood box in his hand.

Chen Chaoyan and Xie Xuan looked at him together.

"Miss Chen, what do you think this is?" The yamen servant opened the sandalwood box like offering a treasure, "Does it look like the box containing the white jade four-eared Yi furnace in Master Song's study?"

What does it look like, it is absolutely!

Ruolan brought the wooden box over, and after the yamen servant left knowingly, Chen Chaoyan laughed slightly: "It seems that Ma Huai's house hides a lot of evidence."

Xie Xuan hooked the corner of his mouth: "It is always a good thing to have evidence."

It is indeed a good thing.

In the ensuing search, the yamen servants found three secret letters blaming Song Yanzhong after he and Shi Zhi conspired to kill Zhou Zhongcai in the secret compartment of Ma Huai's study.The handwriting on the letter is the same as that on the loan deed, that is to say, it was indeed written by Shi Zhi.

If Ma Huai's fingerprints were scanned on the secret letter later, no matter how wrong it was, Ma Huai would be imprisoned in the North Prison as the murderer of Zhou Zhongcai.

After the search was over, when Chen Chaoyan followed Xie Xuan out to the outer courtyard, Feng Shoudao also rushed over with a large number of yamen servants.

There were fifty or sixty people in the Ma family, and they were escorted by hundreds of yamen servants on their way back to the prefect's mansion, attracting the attention of countless people.

Mrs. Zhou also rushed over after hearing the news.

Standing in the crowd, looking at the Ma family being escorted, she couldn't help crying.

When Chen Chaoyan returned to the Sheriff's Mansion, she went straight to the mortuary.

Old man Sun had already placed Li Er's corpse upright on the wooden board, and the tools for autopsy were also placed beside him one by one.

It took Chen Chaoyan more than half an hour to check the cadaver form, and after the autopsy, Yuejian dragged her through the post-autopsy process of removing the obscurity, and it was Shen Shi.

She hasn't had lunch yet.

"Master, Banxia and Ziling have already prepared the meals, hurry up and eat." Yue Jian saw that she was rubbing her stomach, pouring tea, and looking at the bloody handkerchief she brought back after the autopsy, so she couldn't help but go forward and use it. Paper wrapped the bloody handkerchief and urged her, "After dinner, there is still time!"

"Okay." Chen Chaoyan was indeed hungry.

Putting down the teacup and going to Muyuan Hall, Xie Xuan had already prepared meals.

And today's meals are extraordinarily rich.

There are two more meat dishes than usual, and four more desserts.

Chen Chaoyan was not polite to him, sat down at the dinner table and started eating.

After eating and drinking enough, he leaned against the back of the chair to rest for a while, and after briefly explaining the results of the autopsy to him, he got up and went to the desk, and at the same time ordered Yuejian to take out the secret letter, and at the same time ordered Chonglou to prepare the pot ashes .

Yuejian has been following her for quite a while, and has learned how to protect evidence.Wrap the secret letter in a handkerchief, unfold it carefully, and place it in front of her one by one.

Chonglou didn't scrape the pot ash, but under Xie Xuan's signal, he took out more than a dozen boxes containing Danmu, opened them one by one and put them in front of and behind her, and took out two feather brushes and two row brushes. brush.

"I know copper powder and iron powder. This is..." Chen Chaoyan looked at the powder boxes arranged in a row, picked up one of the boxes containing golden powder in surprise, and asked tentatively, "Gold powder?"

"Gold powder, silver powder, copper powder, iron powder, tin powder, lead powder, cinnabar, green alum, blue alum, alum." Xie Xuan introduced lightly, "Stork hair brush, goose hair brush, squirrel hair brush."

"Try it and see if it works."

Real gold powder, real silver powder... really rich!How thoughtful!After Chen Chaoyan clicked twice secretly, picked up the copper powder, dipped it with her fingertips and rubbed it, looked at the fine powder, said very satisfied, "Not bad, very good."

"Try it." Xie Xuan urged.

After Chen Chaoyan said 'hmm', she sat down solemnly, wrapped a corner of the secret letter in a handkerchief, picked it up, and looked at the contents on it again.

The handwriting on the secret letter is Shi Zhi's.

The content of the secret letter recorded in detail the entire process from the time they determined to murder Zhou Zhong, to formulating a plan, to perfecting the details, and how to frame Song Yanzhong.

It can be said that as long as the fingerprints of Ma Huai and Shi Zhi are scanned again, these three secret letters will become ironclad evidence for his conviction!

Putting down the secret letter, Chen Chaoyan picked up a squirrel brush, dipped it in a small amount of copper powder, took one of the secret letters, and slowly brushed it in the order from left to right and top to bottom.

Copper powder is actually gold powder commonly known as trace inspection.

Earlier at Zhou's house, she was afraid that he would misunderstand that it was real gold powder, so she called it back her real name, copper powder. She didn't expect that if he didn't prepare it, he would prepare it, regardless of whether it was real gold or real silver.

As a result of such arrogance, fingerprints appeared after only a few swipes.

Seeing the fingerprints, Xie Xuan glanced at her, and immediately ordered: "Go and find Ma Huai's fingerprints!"

Shi Shu and Wen Mo responded in unison, then turned around and went to the bookshelf where the fingerprints were placed, and began to search for Ma Huai's fingerprints.When they found it, Chen Chaoyan had almost finished fingerprinting.

The three sealed letters, the front and the back together, produced a total of more than 80 fingerprints.Except for the unrecognizable ones, there are 53 left.

Chen Chaoyan had Ma Huai's fingerprints on his screen, but he still accepted the fingerprints from the servant.He held up the secret letter and Ma Huai's fingerprints to the level of his eyes, pretending to find the common place on the fingerprints, but actually looked at the light screen.

On the light screen, Ma Huai's fingerprints were compared with the fingerprints on the confidential letter one by one, and one by one was eliminated. Just when Chen Chaoyan was a little relieved, two fingerprints overlapped at the same time!Immediately after the third, fourth... After comparing the three secret letters, a total of 29 fingerprints were compared!

Chen Chaoyan was only surprised for a moment, then calmly picked up the pen and ticked off the 29 fingerprints one by one.

Xie Xuan played with taste: "Compared?"

After Chen Chaoyan nodded, she asked Yue Jian to find out the deed.The few fingerprints on the deed that could not be compared were compared with the remaining fingerprints on the confidential letter.The result was no surprise, and more than a dozen pieces were compared.

The few fingerprints that have not been compared on the deed have been tacitly left by Shi Zhi.

In other words, the three secret letters can be used as ironclad evidence to designate Ma Huai as the murderer.

It's just... There are still more than ten fingerprints left on the secret letter that have not been compared.

There was a third or fourth person who took these three confidential letters!

Xie Xuan asked Lingyou to extract the fingerprints of everyone in the Ma family, while Chen Chaoyan quietly used the fingerprints of the Sheriff's Mansion, Yingou Cabinet Square and others stored in the light screen to compare them one by one.Surprisingly, none of them matched!

Chen Chaoyan was planning to tell Xie Xuan the result, when he raised his eyes to meet his inquiring eyes, and also the fingerprints of everyone in the Sheriff's Mansion and Silver Hook Cabinet Workshop beside him... quietly avoiding his gaze, and then After dragging all the fingerprints, Chen Chaoyan said calmly: "I was thinking about the case just now, and I was a little lost in thought for a while. What the prince said, please say it again."

Xie Xuan looked at the secret letter in her hand, and asked with a half-smile: "Because the result is different from what Ms. Chen thought, so Ms. Chen is unhappy?"

"The result was indeed beyond my expectation, but the detection of the case has always been based on evidence," Chen Chaoyan said calmly, "Since the evidence points to Ma Huai, the fact that he is the murderer is irrefutable. But... the evidence Although it has come out, the time and motive of committing the crime have not yet been revealed, so we still cannot take it lightly."

Xie Xuan tapped his hands and tapped on the table, "Whose are the remaining fingerprints?"

Chen Chaoyan glanced at the fingerprints of the Sheriff's Mansion and the Silver Hook Cabinet Workshop, but said nothing.

Xie Xuan followed her to look at the fingerprints of the Sheriff's Mansion and Silver Hook Cabinet Workshop, but said nothing.

It wasn't until Lingyou brought back the fingerprints of everyone in the Ma family that Chen Chaoyan persisted for about half an hour before saying, "These fingerprints can't match."

Xie Xuan still didn't speak, but only lowered his jaw to signal her to continue comparing the fingerprints of the Ma family.

After three more teacups, Chen Chaoyan put down the last fingerprint, "It still doesn't match."

"If you're not right, then you can't be right." Lingyou said casually, "There are Li Er's body, the hemp rope that was strangled, the bloody handkerchief you found from Li Er's arms during the autopsy, and the blood in Li Er's stomach. The food remnants in Zhou Zhongcai's stomach that have not had time to digest, as well as evidence such as fingerprints on these sealed letters, are enough to convict him."

Yuejian clapped her fingers aside and added: "Ms. Chen's portrayal of the murderer earlier: Familiar with the human body structure, capable of anti-investigation, participated in the massacre of the Bao family, martial arts, fingerprints on the lease, etc., he are also satisfied."

"Then there's no need to check anymore, he's the murderer!" Lingyou stacked all the fingerprints together, and asked Shi Shu and Wen Mo to quickly take them away, and said, "Those fingerprints that don't match up are probably his accomplices." .When we go back to the trial, let Mr. Feng ask you and you will know."

The word accomplice reminded Chen Chaoyan that there was a person whose fingerprints hadn't been compared yet!

Xie Xuan obviously thought of it too, first she ordered Ling You: "Go and extract Li Er's fingerprints."

Lingyou went away muttering.

After coming back a little while, Chen Chaoyan took the fingerprints for a while, and then said: "It's matched!"

It's just that there are three more that don't match up.

Ling You clicked his tongue, "This Ma Huai is amazing. First, he partnered with Shi Zhi to kill Zhou Zhongcai, then partnered with Li Er to kill Shi Zhi, and finally killed Li Er by himself. If it wasn't for Miss Chen who could solve the case with fingerprints, it would be really amazing. He escaped."

Chen Chaoyan reminded him: "There are still a few of these that can't be compared, and the time and motive of committing the crime have not yet been revealed."

"It's simple, I'll find out when I go to the North Prison and ask him." Ling You volunteered.

however……

Ma Huai did not admit the fact of the murder.

but!
